No Start, No Crank, Intermittent Electrical Operations (Check for Poor Connections Within Engine Wiring Harness Junction Block)

Some customers may comment on a no start, or no crank, or intermittent electrical operations.

This may be caused by probing fuse or relay connectors with incorrect J-Tools, which causes splayed terminals and poor electrical connections. Customers may also have installed wires adjacent to the fuse connector blades in order to create an electrical circuit, which also creates a potential loose connection at the fuse. Other potential causes are probing by independent repair shops during installation of aftermarket accessories like remote start systems.

If the terminals are damaged beyond repair, the engine wiring harness junction block will have to be replaced.

Be sure to use the correct J-Tool (J-356616-35), which is designed to prevent splaying of the terminals and loose connections.

Important: DO NOT use any other device (incorrect J- Tool, multi-meter probe) to test fuse/relay terminals.

The figure below shows splayed fuse terminals due to probing with a round instrument, which caused a poor electrical connection between fuse blade and terminal (note lack of witness mark on fuse blade).

The figure below shows a wire jammed into fuse slot (potential electrical tap by customer).

This repair will not be covered under warranty due to damage/failure caused by inappropriate probing or customer abuse.
